TUBING AND rackn'veron OIL-WELLS.

To all whom it may concern Be it known that I, ALBERT J. MGNALLEN, acitizen of the United States of America, residing at Gore, in the countyof Hocking and State of Ohio, have invented certain new and usefulImprovements in Tubing and Packing for Oil-Wells, of which the followingis a specification.

The present invention relates to tubing and packing for oil wells, andis designed especially for the purpose of improving the construction ofthe packing and joints in the well tubing and barrel of the oil pump inorder to prevent waste or loss of oil, and make the glands and packingmaterial'tightfitting in their tubes.

The invent on conslsts essentially in certain novel combinations andarrangements of parts for accomplishing the above purpose as will behereinafter more fully described and claimed, reference being had to theaccompanying drawings in which I have depicted one form of the physicalem-' bodiment of my invention which has proven highly satisfactory andefficient. I

Figure l is a partial sectional and partial elevation view, showing theupper end of the oil pump tube and oil outlet therefrom and the pumpbarrel and cable, showing also thesocket at the lower end of cable. Fig.2 is a sectional view on line A-A of Fig. 1. Fig. 3 is a View similar toFig. I

2 but showing the jaws of the clamp device opened, to give access to thesectional parts of the gland. Fig. 4 is a plan view of the upper end ofthe oil well tube showing the sectional gland therein. -Fig. 5 is anenlarged detail sectional View, showing the manner of securing the cableto the socket.

In illustrating the construction and application of my invention I haveutilized the usual oil tube 1 forming part of the pumping device andincluding the T sec tion or coupling 2 with the oil outlet 3 to whichthe bushing 3 is connected by the threaded coupling sleeve 4.

The bushing as clearly shown is open at the top and formed with a pairof perforated and threaded ears or lugs 5, 5, projecting from its upperedge, while near its lower end, which is of reduced diameter,

an annular shoulder 6 is fashioned upon which shoulder the lowersections 7, 7 of the packing gland are seated. The upper sections 8, 8,of the gland are separated from the lower sections 7 by the packingSpecification of Letters Patent.

material 9 of suitable type or character, and each of the four glandsections is formed with hemispherical'grooves for the free movement ofthe pump barrel 10 which reciprocates through the packed gland.

To hold the glands and packing securely in the bushing, I employ aclamping member comprising the two hinged jaws 11 and 12 which freelyswing on the threaded bar or bolt 13 as their pivot. This bolt isadapted to thread into one of the ears 5 Erica. V

of the bushing and has on its upper end a 'locknut l4 and clamp nut 15,the latter bearing upon the top edge of the jaws at their hinged joint.In Figs. 2 and 3 it will be seen that these jaws are provided'withcurved portions 11"and 12 which fit around the barrel 10, but do notinterfere with the movement of the barrel. At their ends the jaws areclasped by means of the yoke 16 which is fixed to the jaw 12 by the bolt17 and detachablyconnected to the jaw 11 by the bolt 18. In Fig. 1 itwill be seen that 'the longer jaw 12 is provided with a slot 19 near itsend in which the bolt 17 is slidable, and by this means the yoke may bemoved to clasp over the end of the shorter jaw 11, or moved outwardlyto. free the jaws from each other. When the jaws are brought togetherthey fit .about a threaded bolt 20 which is threaded into the other ear5, and this bolt is also provided with a clamp nut 21 and lock nut 22.Thus, when the parts are assembled as in Fig. 1, the gland sections maybe securely pressed down in the bushing by turning the clamp nuts on thebolts 13 and 20, and then these nuts may be locked against turning bythe lock nuts 14 and 22. The jaws thus bear upon and hold the glands inthe bushing forming an air and oil tight closed top or housing for theoil tube and preventing the escape of oil therethrough.

Above the packed joint or housing a similar but smaller'bushing 3 isscrewed to the barrel 10 and'the gland sections 7 and 8 and clampingmember 13 provide a tight joint for the cable 14 and provide a liquidtight joint. The cable of course may the pumping sinker has reached itsdesired depth, and then the cable may be clamped and held between theclamp member 13' as will be understood.v

In Figs. 1 and 5 the improved manner of fastening the socket 23 to thespread end pass down through-the packed gland until of separate strands24 of the cable 14" per- 10, thus avoiding the usual necessity of cut- Qting the socket from the cable before it can be passed through thebarrel.

The socket is threaded externally to receive the sinker (not shown), andperforations are formed in the socket to receive the'unraveled endof-the-cable which is then leaded or babbitted to make a securefastening.

The jaws of the hinged clamps may be opened to give access to the glandsof the packing and the sectional construction of these glandsfacilitates the replacing and renewing of worn parts without recourse tothe usual laborious proceeding, thus sav-,- ing considerable time andexpenditure of energy, in attending to these duties.

What I claim is:-

The combination with an interiorly shoul-- dered oil Well tube providedwith exterior perforated cars, a sectional packing gland in the tube,and threaded bolts in the ears,

of 'a pair of clamping jaws having a hinge ture.
